STIM map: detection map for exoplanets imaging beyond asymptotic Gaussian residual speckle noise
Benoît Pairet, Faustine Cantalloube, Carlos A. Gomez Gonzalez +2
Direct imaging of exoplanets is a challenging task as it requires to reach a high contrast at very close separation to the star. Today, the main limitation in the high-contrast ima…
SPHERE / ZIMPOL high resolution polarimetric imager. I. System overview, PSF parameters, coronagraphy, and polarimetry

Cyprien Lanthermann, Jean-Baptiste Le Bouquin, Narsireddy Anugu +2
We characterize a near-infrared C-RED ONE camera from First Light Imaging (FLI). This camera uses a SAPHIRA electron avalanche photo-diode array (e-APD) from Leonardo (previously S…
Low Wind Effect on VLT/SPHERE : impact, mitigation strategy, and results
Julien Milli, Markus Kasper, Pierre Bourget +14
The low wind effect is a phenomenon disturbing the phase of the wavefront in the pupil of a large telescope obstructed by spiders, in the absence of wind. It can be explained by th…
